This was our first time at this office with this provider and we had a wonderful experience!

He showed interest and compassion and made myself and my daughter feel at ease and confident that he was dedicated to treating her particular situation.

Doesn't get better then Doctor Nash. He is top notch. I have recommended him to friends because we think so highly of him.
We have finally found a doctor that knows what is truly going on with our daughter and her allergies, reactions, and eczema. He is undoubtedly helping my daughter and making her life so much better!

Really great experience!!
dr Nash has always provided excellent care.
made my daughter very feel comfortable
Dr. Nash is a wonderful doctor who spent a lot of time explaining care plans and had a great way with my son. He helped me to understand his allergies and how to manage his care. I have recommended him to everyone and my niece is now also a patient with him based on my recommendation.
Dr. Nash was wonderful!! I was very impressed with the effort he made to connect with my son. He took the time to explain the tests and make him (and me) feel comfortable.
we felt like both Dr Nash as well as Nurse Jamie? were very concerned for our daughter and took special care of her and worked well to keep her fears minimal. I feel that they both went above and beyond to make our first and hopefully last experience with allergy testing a lot easier than it could of. they both went out of their way to build a relationship with my daughter to out her at ease. I give them both an A+++++++
I was very impressed with Dr. Nash.

Fantastic experience . Dr Nash made all of us very comfortable and eased our concerns about our son.
Dr. Nash possessed a confidence in his abilities and in his knowledge of what were were dealing with. This was very comforting to me.
First visit - very impressed and pleased with the doctor!
We have seen Dr. Nash for years and truly feel his is one of the best doctors we have ever seen. I wholeheartedly recommend him regularly to others. We are always extremely pleased with his care and his demeanor. We think he is super smart and competent but he is able to make common sense decisions that relate to the individual child. I think that is not always easy to find with physicians.
Changing our allergist to Dr. Nash has been life changing! My little girl is doing so much better! We are undoubtedly so happy we found Dr. Nash and his nurse Tammy! Thank you!!!!!!
Dr. Nash was very polite and directed lots of questions towards my son, not just me. i appreciated that Dr. Nash included my son in the conversations.

DR. NASH IS EXCELLENT. HE IS VERY THOUROUGH AND KNOWLEDGABLE. HE EXPLAINED EVERYTHING AND CHECKED FOR UNDERSTANDING/ALLOWED ME TO ASK QUESTIONS. I WAS VERY IMPRESSED WHEN I HAD TO CALL THE ALLERGIST ON CALL AND THEY TOOK THE THE TIME TO PROVIDE ME WITH ENOUGH INFORMATION TO FEEL CONFIDENT IN MY CHILD'S TREATMENT AND DR.

Dr. Nash and his staff were wonderful and made me and my daughter very comfortable. I was very pleased with the entire visit.
Very good experience.The doctor explained the results of my daughter's tests,and treatment plan that would be most helpful.
Dr. Nash was concerned about the comfort of our child and putting him at ease, even remembering to call him by his nickname. His notes and medical records are very thorough, and he does an excellent job of explaining our child's condition to us (and to our child) and making sure we are trained to manage it at home. Overall, the protocol is very clear and effective, and the office is well run. Couldn't ask for more! Highly recommended to fellow allergy families!
